cane? 1Q 5'14 22 A'I'I'ORNEY5 United States Patent PEELABLE LIQUID PLASTIC COT OR BANDAGE Francis vD. Sullivan, Memphis, Tenn.; Mary E. Sullivan, heir of Francis D. Sullivan, deceased Application June 6, 1952, Serial No. 292,071 1 Claim. (Cl. 128-157) This invention relates to finger cots, bandages, and the like coverings and protectors for the hands and other parts of the body, for protective covering of wounds and as a protection against abrasions, punctures, splinters, pressure sores and burns in the handling of small parts and particles of material, glass slivers, very 'fine wire, soldering irons, and the like situations where protection is desired and especially where it is necessary to retain feel or sensitiveness and avoid slip or friction, and have water and moisture resistance at the same time, all as distinguished from those known ordinary coverings which are neither waterproof nor permit retention of feel, etc., as described, or if waterproof do not have the desirable other characteristics enumerated as present in my inventron.

The desirable objects of my invention may be accomplished in any of several ways, these all having the same essentials which include ease of application and removal and without limit as to specific dimensions, perfect adherence and resistance to the effects of perspiration. Furthermore, coloring may be added to match the tones of the skin or it may be clear and it may be of substantially any desired thickness and applied in a variety of ways, as will hereinafter be more specifically described. If so desired, antiseptics, fillers, pigments, and the like may be added.

With the foregoing and other objects which will be apparent from the following disclosure, my invention con sists in the matters hereinafter set forth.

In the drawing:

Figure 1 is a fragmentary side elevation of a finger having a finger cot mounted thereon according to an embodiment of this invention.

Figure 2 is a fragmentary sectional view showing the material of which the finger cot is formed mounted on a glass plate.

Figure 3 is a sectional view similar to Figure 2 but showing the plastic material combined with a fabric.

Figure 4 is a detailed side elevation of an outer finger cot constructed from combined plastic and fabric material.

Figure 5 is a longitudinal section showing the cot disclosed in Figure 4 mounted on a finger with an inner cot secured to the outer cot and the finger.

Figure 6 is an enlarged fragmentary sectional view showing finger cot forming material produced from com bined plastic and fabric.

Figure 7 is a fragmentary side elevation of a finger having a band-shaped cot mounted thereon.

Referring to the drawing, the numeral 10 designates Percent, approximately Polyvinyl copolymer resin 18.2 Plasticizer 5.4 Aluminum powder 3.6 Methyl ethyl ketone solvent 71.8'

Propylene oxide 1.0

The liquid compound set forth above may be. formed into the cot 10 by dipping or extending the finger into the liquid composition and letting the material set or harden. The thickness of the material is determined by the number of times the finger is dipped into the composition material so that any desired thickness of a finger cot may be obtained.

Where it is desired to have a finger cot formed of combined fabric and plastic, the liquid composition is poured onto a fabric 12, as shown in Figure 3, which is disposed on a smooth surface such as a glass plate 13. The impregnated fabric may be peeled from the glass panel or plate 13 and may then be formed, as shown in Figure 4 into a finger cot 14 by stitching 15. The fabric 12 will form a relatively rough outer surface which, in certain instances, is desirable in the finger cot.

The outer cot member 14 is applied to the finger by initially dipping the finger in the liquid plastic material so as to form an inner relatively flexible cot member 16. Before the inner cot member 16 becomes set, the outer cot member 14 is extended over the finger so that the inner and outer cot members will amalgamate or combine with each other. In this manner, the outer cot member 14 will be firmly held to the finger, but can be removed when desired by peeling the same from the inner end thereof.

The cot forming material may also be used for other purposes and may be converted from liquid form to solid or pliable, flexible form, as shown in Figure 2, by pouring the liquid plastic material on a glass plate 17, as indicated at 18. As many pourings may be made on the plate 17 as may be desired to produce a flexible plastic sheet of desired thickness.

The formula hereinbefore given may have any desired pigments or fillers added thereto for producing a cot forming material of a desired color. The proportion of the pigments or fillers may also be used for controlling the viscosity of the liquid material.

The finger cot, such as the one shown in Figure 1, is particularly desirable where relatively small articles are to be handled, such as glass slivers, splinters, very fine wire, soldering irons or the like, which normally cause punctures, pressure sores, or burns. The finger cot as hereinbefore described will firmly and smoothly ad here to the skin, closing the pores, and will give a kid glove feeling and remain free from perspiration, will not irritate the skin, and will protect the cuticle.

Referring now to Figure 7, there is shown another modification of this invention wherein a plastic band 20 formed of the material hereinbefore described is mounted on a finger inwardly from the nail 21. The band may be initially molded as a complete band or may be formed by producing a narrow strip on a flat surface and the ends of the strip cemented together by suitable cement or by applying the liquid plastic to the strip ends.

The cot shown in Figure 1 may also be initially formed in a mold to produce the desired thickness, and the molded cot can then be secured to the finger by dipping the finger in the liquid plastic and applying the cot over the coated finger before the coating sets.

The cot can be easily and quickly removed by peeling the same from the inner end and may also be reused. One of the particular advantages of the cot hereinbefore described is that the cot may be made relatively thin where a sensitive feeling is to be retained in the finger.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.

What is claimed is:

A finger cot removable from said finger in intact condition'for subsequent reuse, said cot being formed from plastic material having skin adhesive and antiseptic characteristics, said cot being substantially hollow, and said plastic material having substantially the following components:

Percent Polyvinyl copolymer resin 18.2 Plasticizer 5.4 Aluminum powder 3.6 Methyl ethyl ketone solvent 71.8 Propylene oxide 1.0
